The Shift Toward Automation in NDT

Traditional non-destructive testing inspections were performed using rudimentary tools requiring significant human intervention and subjective judgment. Modern NDT software solutions have evolved this experience, by integrating different inspection methods into seamless, data-driven workflows.

What is an NDT software?

NDT software are integrated platforms that support the storage and analysis of inspection results and generate detailed reports and scheduling, whilst handling other tasks. Automation and Data Management incorporate predictive analytics, 3D modelling, and real-time defect visualisation for faster and more reliable inspections in many industries. These NDT solutions align with the rising emphasis on safety, reliability, and performance in the field.

Technical Challenges in Traditional NDT

Modern tools like management platforms, workflow management software, and automated NDT systems help overcome the challenges experienced in traditional NDT practices that significantly affect the outcomes of inspections. Some of the demerits of traditional practices in NDT that can be combatted by integrating data management and automation include:

1. Manual Data Errors:

Manual data handling in traditional NDT workflows often causes issues affecting the inspection process.

• Data Handling: Traditional NDT methods like Phased Array Ultrasonic Testing or digital radiography generate large datasets. Manually handling this data increases the likelihood of errors like inconsistent labelling of defect locations or inaccurate depth readings. This can result in defects being neglected.
• Human Limitations: Repetitive manual tasks, such as logging thousands of inspection points in large structures cause inspector fatigue, leading to errors. Data transcription errors are common when inspectors switch between digital equipment and paper records.

NDT data management tools incorporate built-in validation algorithms to reduce human oversight in reporting. The standardised data formats in these systems ensure seamless integration across devices.

2. Scalability Issues:

Scalability is a major concern for industries requiring large-scale inspections.

• Complexity of Assets: The intricate geometries, extensive pipelines, and complex equipment in modern industrial facilities require thousands of individual inspection points. Traditional methods fall short of providing a clear framework for consolidating and analysing data from these numerous inspection sites.
• Diverse Inspection Techniques: Large-scale operations typically employ multiple NDT Techniques with varied data formats. Managing these without a centralised system leads to inadequacies.
• Data Fragmentation: Data collected from different sites and methods is often stored in isolated silos. This makes it difficult to aggregate for trend analysis or long-term maintenance planning.

Workflow management software centralise the inspection processes, supporting Cloud-based data storage, and enabling remote access and collaboration across multiple sites. 

3. Inconsistent Reporting Standards:

• Reporting Practices: Inconsistent criteria for defect interpretation by inspectors may lead to unreliable data. 
• Reporting Cycles: Manual consolidation and approval processes slow down the delivery of inspection results which delays maintenance activities.

Automated NDT reporting systems use pre-configured templates aligned to industry standards like ISO or ASME. These systems ensure uniformity and comparability across inspection reports.

4. Costs and Time Inefficiencies:

Traditional workflows may often involve high costs due to labour, equipment utilisation, and data processing.

• Labour-Intensive Processes: Manual data entry, interpretation, and reporting require significant staff hours, diverting resources from inspection activities.
• Repeat Inspections: Errors or incomplete results in initial inspections necessitate repeat testing, increasing downtime and operational costs.

NDT management platforms streamline operations by automating repetitive tasks such as data logging, processing, and reporting. Predictive maintenance, supported by advanced analytics, minimises unnecessary inspections and optimises asset Lifecycle Management.

5. Limited Predictions: 

Isolated historical and real-time data prevents trend Analysis and Predictive Maintenance planning. This increases the risk of sudden asset failures, which could be catastrophic in aerospace and power generation.

NDT Process automation tools incorporate machine learning algorithms that analyse historical data trends to predict potential failures. NDT data management tools enable operators to establish baseline conditions, allowing for automated alerts.

6. Human Limitations:

High-temperature or radioactive environments pose risks to personnel. Accessibility challenges, such as inspecting deep subsea pipelines or Confined Spaces, further complicate manual inspections.

Remote-controlled automated NDT systems reduce the need for human presence in dangerous environments. Integrating robotics and drones enhances access while ensuring inspector safety.

7. Data Archiving and Retrieval:

• Lack of Centralised Storage: Traditional methods often rely on paper records or unstructured digital storage systems, making retrieving past inspection data for analysis difficult.
• Loss of Institutional Knowledge: Poor data archiving practices result in the loss of valuable knowledge when personnel leave or inspection records are misplaced.

Modern NDT Inspection software provides structured, centralised databases for secure data archiving. Advanced search capabilities make retrieving historical data quick, enhancing long-term asset monitoring and decision-making.
